What radio gear are you using? Can you set your throttle response profile on the tranny instead? Personally I use the linear profile on my tekins, but I have played with exponential throttle curves on the tranny.
To smooth-out power delivery I use the "current limiter" setting on the "Throttle" Tab. This does not effect top end speed, just the harshness of power delivery when pushing the trigger. It help in low traction tracks.
I usually run 70-80 on my B4.1/C4.1, but have gone as low as 50 at the oople race to try help tame my trigger finger. I've now switched from a spectrum wheel radio to KO sticks and found it much much better in that respect.
